DETERGENT FOR SCOURING wooL.

To all whom it may concern:

Be it known that I, SALO WOHLE, a subject of the German Emperor,residing in London, En land, have invented certain new and usefullmprovements in Detergents for scouring Wool of which the following is aspecification.

In accordance with my invention a mucilflgfiwus q such as coetiex npsaa. is mixed with a fat or fatty'oil, such as castonoil, and withsaponin, which may be added either as such or b "digestin the decoctionwith the addition 0 soda, pre erably carbonate of s da, with a materialcontaining saponin, suc as horse-chestnuts, acacia s opr ta; nuts. Tothe mixture tlius made' 1s added @me hydrogen peroxid or materials whichproduce itfsuch'asa vegetable acidoracid salt, and a suitable peroxid.For example, two and one 'halfpound's' of linseed or threefourths of apound of other vegetable material yielding mucilage are boiled with fivegallons of water and the decoction is strained and there is addedan'extract made bydigesting twelve and one-half pounds of strippedhorse-chestnuts with five gallons of water to which carbonate of sodahas been added, or the linseed and horse-chestnuts may be digestedtogether and the decoction strained. About one-half pound of a fattyoil, preferably caster-oil, is now added, followed by about one ounce ofafeeble acid, such as a c e t ic acid or an acid salt,like salts oflemon, and about one and one-fourth ounces of some suitable peroxid,(preferably in solution,) such as sodium eroxid. This liquid is nowready fol;- use as a detergent for scouring Wool or the The above recipeis suitable for fine wools. Coarser varieties needmore saponin than isobtainable from horse-chestnuts. For these,

therefore, there may be added to the above mixture saponin from anysource-say on the same scale of proportions, ten pounds.

The essential ingredients of the detergent are the mucilaginousvegetable matter and the saponin. A vegetable acid is advantageous, andthe eroxid is useful in yielding hydrogen peroxi which may of course besu stituted for it.

By use of this deter ent the wool grease is removed from the woolwithout being saponified and is therefore easily recovered. The wool isat the same time made more flexible than in the ordinary scouringprocesses and requires less oil in spinning. Moreover, the yolk remainsin the wool, which is therefore of better weight.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to beperformed, I declare thatwhat I claim is- 1. A detergent for scouring wool made from a decoctionof a vegetable material yielding mucila e, to which vegetable saponin isadded, as wellas small quantities of a fatty oil, a feeble vegetableacid, and peroxid of sodium.

2. A detergent for scouring wool, comprising a decoction of vegetablematerial yielding mucilage, an extract of strip 'ed horse-chestnuts towhich carbonate 0 soda has been added, a fatty oil, a feeble vegetableacid, and sodium peroxid, combined in or about the proportionsspecified.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
